REED-ORGAN.

SPECIFICATION forming part of Letters Patent No. 253,393, dated February 7, 1882.

Application filed October 18, 1881. (Model.) Patented in Canada April 29, 1881.

To all whom it may concern Be it known that I, GEORGE B. KELLY, of Boston, in the county of Sulolk and State of Massachusetts, have invented certain new and useful Improvements in Reed-Organs, otl which the following is a full, clear, and exact description.

This invention has for its object the production of a reed-organ that is simple in its con- Io struction, neat and tasty in appearance, practical and instructive in its use, its various elements constructed and arranged in a compact form, and so arranged and connected together as to be capable of being readily and easily taken apart and packed in a small compass for convenient transportation, and also one that can be manufactured at a cheap cost, all substantially as hereinafter fully described.

In the accompanying plates of drawings zo this invention is illustrated, Figure l, Plate l,

being a perspective view of a reed-organ constructed according thereto 5 Fig. 2, Plate 2, a vertical transverse section from front to rear of the organ; Fig. 3, Plate 3, a vertical section of the bellows and its exhausters on line 3 3, Fig. 2; Fig. 4, a plan view of a few keys of the key-board, Fig. 5, a vertical section on line 5 5, Fig. 4; Fig. 6, a detail sectional view; Fig. 7, Plate 4, a front elevation, showing some 3o of the parts detached; Fig. 8, an inside elevation of one of the supporting-uprights; Figs. 9, 10, and 11, views in detail, to be hereinafter referred to.

In the drawings, A A represent two par- 3 5 allel standards or uprights, which are made ot' any suitable ornamental outline and at and between their upper parts carry a box or casing, B. This box or casing consists of front and back upright boards, t b, secured by screws 4o c or otherwise to upright end pieces, d, bottom board, s', and a top board, e, extending over the back portion of the box, which is secured by screws c, 85e., to the upper edges of the back and end pieces, and to the front edge of which, at f, is hinged a lid or cover, C. This box, at its ends, rests on horizontal transverse flanges or strips D on inside of uprights, be-

ingattached and held in such position by sockets g in end pieces, d, which lit vertical pins h 5o on the transverse strips, and screws Z, screwing into the upper part of the uprights, whereby the case is held firmly to the same. In this box or casing B are arranged the several elements which go to make up the reed-organ, consisting in substance of a bank of keys, E, a set of valves, F, and reeds G to such keys, a windchest, H, bellows J, and two separateexhausters, K and K. The keys E are at the upper part and along the front of the casing B, and they there are arranged in the usual order.

The lid or cover O is to coverthe keys when so f desired. The edge m of the lid G and the front edge, n, of the top board, e, are respectively beveled, as shown, so that when the lid is opened and swung back the bevel edge will rest and be supported against the beveled edge u ofthe top board, and all in a manner to place the said lid at a suitable angle of inclination to act as a music-desk, for which purpose it is provided with a projecting ljange, o, in suita- 7o ble position for the then rest of the lower edge of the music sheet or book upon it. The flange o, when the hinged lid is closed, projects from the inner face, and the lid at each end when closed rests upon the edges p ofthe ends d of the casing, andit has au inclination toward the frontend ofthe keys, which inclination is sufficient for the liange to clear the internal parts of the organ.

Two arms, q, pivoted at r to the inner face 8o of the lid, and connected together by a crossarm, s, pivoted thereto, when swung up as shown in Fig. l, serve as an extension ot' the lid for the better support of the music-sheet, being swung down when desired to close the lid. L, a stationary horizontal inclined frame below the keys E, constituting the key-frame. This frame at and along its rear portion, t, has a series of fixed vertical pins, u, one to each key. The inner end of each key has an open 9o horizontal groove, e, into which projects by its horizontal edge w a strip, M, secured to the rear edge of the-frame L, which serves to hold the rear ends ofthe keys in place on the frame. Each pin a passes through a round'95 hole, m, in the lower portion of the key leftby the groove, and a longitudinal vertical groove, y, in the upper portion of the key, which groove allows for the movement of the key in its operation. Each key toward its roo front end has a vertical pin, a', rigidly secured to it, and extending downward enters into and plays within a slot, b', in the front part, c', ofthe frame L. This slotl is made by vertically sawing or burring into the rear edge of the front portion, c, at the points desired, the frame heilig cut away at such edge on its under side, as at d', reducing its thickness at suoli portion to thereby diminish the friction of the pinsuin their movements in and through the slots b as the keys E are operated.

To prevent the breaking of the portions f between the slots, which might occur on account ofthe slot being ont across the grain oi' the wood, a strip, g', is glued onto the same, as shown in Fig. 6 more particularly. This arrangement ofthe keys constitutes their hanging, and itis plain that it is simple and effective, and such as to give a free and steady movement to the keys when played upon, secures a key of reduced thickness from keys as now niade, and in connection with the arrangement of the pin for guiding the key enables the frame and keys to be manufactured at a much less cost than heretofore. Each key rests upon a vertical valve-stem, It', which in turn rests upon the valve F, having a spring, m', to the organ-reed Gr, and the several valves open inwardly to a common wind-chest, H, l0- cated below the valve.

The bellows J is located below the windchest H, forming a continuation of the same, and below and under the bellows are located the two exhausters K and K', connected to the board s', which are arranged to work separately and distinctly from each other and to open and close in a vertical plane.

a are passages connecting the wind-chest and the bellows and the exhausters K K at their rear ends, through which passages the air passes from the bellows to the exhausters when they are operated to exhaust the same, the bottom board, of, of the bellows as it (the bellows) is exhausted being raised against its springs p', its sides q being iiexible for such purpose. The springs p act to force the board down to insure the opening of the bellows for the air which has passed through andsounded the reeds to pass into the bellows to be exhausted therefrom in the continuous operation of the exhausters.

r are openings in the bottom board, s', through which the air exhausted from the bellows by the exhauster through passages a escapes into the open air in the upward movement of the exhausters, a valve, t', freely allowing of such and preventing entrance of air when the exhauster is opened to exhaust the bellows, valves a over v the passages fn operating in a similar manner between exhausters and the bellows.

The several parts above described are all within the compass ofthe box or casing B, except the exhausters,which are on the under side of the board s.

Each exhauster is operated from a distinct and separate foot-treadle, P P,which treadles are arranged side by side and turn upon pivotsa", at or near their middle, on a supportingrail, O, connected to the lower ends of the uprights. At their inner or toe ends, v', they are connected to their respective exhausters K K by suitable connecting-rods, w to2, one rod to each exhauster and its treadle. These rods at their ends are bent at right angles, as at a, which right-angular parts turn respectively in horizontal sockets y y2, one, y', in the inner side near the rear end ot' the treadle and the other, y2, in a block, z, 011 the under side of the exhanster, and when in position are held in place by a block or button, b2, pivoted to the block z', which is adapted to swing over and away from the end of rod, and when swung over secure and hold the rod from accidental detachment, and when swung away allow the rod to be detached, as desired. Such buttons can be used to hold the rods to the treadles, if desired. Pressing upon the rear end, e', of the treadle by the toeor ball of the foot of the operator or player through the connecting-rods pulls down the exhausters, exhausting the wind-chestand bellows, and pressing down the other or front end of the treadle by the heel of the operator or player raises the board of the exhausterinto position for anothermovement downward,as before, to again exhaust thebellows, and so on. Each inovementof the exhausters is positive from theoperation ot' the treadle, and each exhauster is free and independent from any spring or springs, as heretofore, and each works independently of and separately from and alternately with the other. Furthermore, the treadles place the action of the exhausters so entirely under the control of the performer that the upward or return movementfof the exhausters can be accelerated or retarded bythe manipulation of the toes and heels of the performer upon the treadles to increase or decrease the pressure thereon, as may be deemed necessary or desirable.

At each end of the rail O is a vertical pin, kc2, to iit a socket, d2, in the bottom end of the uprights, by which the rail() is secured to the upright, and so that it can be attached and detached at pleasure.

Q is the swell-board located at the back of the reed-chamber T, and arranged to be opened against a spring, f2, through the swing of the arm R, which is pivoted to the front et of the organ-case in the proper direction therefor.

S is a rod connecting the arm R with the swell-board, and through which the movement of the arm is communicated to the swell-board.

The end g2 of rod S plays in a slot, h2, in the i i i with the exhausters by swinging the buttons b2, when the ends of the rods can be easily removed from their sockets; then unserew the screws lin the ends of the box and lift the box from the strips which separate the box from the uprights; then detach the treadlerail from the uprights, removing the said rods from their sockctsin the treadles,when the several parts can be laid and packed together in a small compass, as is obvious. Reversing the operation secures all parts together again for use.

A reed-organ constructed and arranged as herein described is simple, neat, and4 tasty in appearance, is compact in form, can be manufactured and sold at a low price, gives for its compass as effective and complete an organ as an instrument of greater cost vand more elaborate in construction, and, being arranged to be easily taken apart and packed in a compact form, can be conveniently transported, as desired, all of which are advantages whicll are desirable, as is obvious.

In lieu of a screw, Z, to secure the case to the upri ghts, other fastenin gs can be employed, although a screw is simple, cheap, and effective; also, in lieu of holding the rods tothe eX- hausters by buttons, any device can be used, although the button serves all purpose, and the strip g can be secured to the frame by screws or otherwise, in lieu of glue, although glue is preferable. Buttons can be used to hold the rods w to2 to the treadles, as shown in connection with the exhauste'rs.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, xs-

l. The combination, in a reed-organ, of the bellows located below the wind-chest and forming a continuation of the same, with the supplementary operating-exhausters K K', connected by rods to toot-treadles, and also connected to the boards s', provided with air-inlets and valves, the air-passages n connecting the wind-chest and bellows, and the exhauster and the spring p' acting upon the bottom board ofthe bellows, said members being constructed and organized substantially as described.

2. In a reedorgan, a key of reduced thickness supported atits rear end by the key board 0r frame, said key being provided with a long pin, a', rigidly secured thereto and projecting downwardly therefrom into a slot in said frame, whereby the key is guided in its movement, substantially as and for the purpose specified.

3. In a reed-organ, a key-frame having a slot, b', in the front portion, c', for the pin a of the key E,in combination with the strip g, secured to the portions f between said slots, substantially as and for the purpose specitied.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

GEORGE B. KELLY.
